'import type' errors from TypeScript in Deno 1.4.0

[solson]

For some reason, when I run Deno 1.4.0's new deno test --unstable --coverage command, I get errors from Fae that didn't previously appear:

$ deno test --unstable --coverage lib_test.ts

Found 4 errors.

I am importing only the zip function, but I assume similar issues would arise in other parts of Fae.

Here's a minimal repro:

$ cat foo.ts 
import { zip } from "https://deno.land/x/[email protected]/zip.ts";

$ deno test --unstable --coverage foo.ts
[... same as above ...]

$ deno --version
deno 1.4.0
v8 8.7.75
typescript 4.0.2

This must be caused by denoland/deno#7413.

Edit: More information in the v1.4 release post.

Thanks for the quick fix! Will the new version automatically show up on deno.land/x? I'm not yet seeing it at https://deno.land/x/[email protected].
